SSL and Plaintext Authentication

If you intend to use SSL, set ssl_cert_file and ssl_key_file settings. Otherwise set ssl_disable = yes (ssl = no with v1.2.beta1+). Easiest way to get SSL certificates built is to use Dovecot's doc/mkcert.sh script. See SSL.

By default Dovecot doesn't allow users to send passwords unencrypted to the server. Usually if SSL is enabled, it's a good idea not to allow this. However, if you don't offer SSL for some reason, you'll probably want to set disable_plaintext_auth = no.

To enable imaps and pop3s, make sure they're listed in protocols setting.
